K:A
5:3 (before)
15:9

since the total number of stamps didn't change, the total ratio should be the same.

7:5(after)
14:10

so this means 1 unit is 10stamps.

14-10=4
4 X 10= 40

Kaye have 40 more stamps than Alberto.

Show that log√7 + log√20 - log√14 = 1/2
Mademuasel [1]

Alright, lets get started.

log \sqrt{7}  + log \sqrt{20}  - log\sqrt{14} = \frac{1}{2}

We could write this square root as \frac{1}{2}

log7^{\frac{1}{2}} + log20^{\frac{1}{2}}- log14^{\frac{1}{2}}

Using the property of logm^{n } = n log (m)

\frac{1}{2}log 7 + \frac{1}{2} log 20 - \frac{1}{2} log14

\frac{1}{2} is common in each term, so

\frac{1}{2}(log7 + log 20 - log 14)

Using property of log m  + log n = log(mn)

\frac{1}{2}(log 140 - log 14)

Using property of log m - log n = log\frac{m}{n}

\frac{1}{2}log\frac{140}{14}

\frac{1}{2} log 10

log 10 value is 1 , hence

\frac{1}{2} * 1 = \frac{1}{2} : Answer

Hope it will help :)

Bob's Bagels sell for 10 bagels for $11.00,and Donny's bagels sells for 4 for $3.00 which is the better deal​
Airida [17]

Answer:

Donny's bagels is the better deal.

Step-by-step explanation:

Bob's bagels are 10 for $11

Unit price for Bob's bagels = $11 / 10 bagels = $1.10 per bagel

Donny's bagels are 4 for $3

Unit price for Donny's bagels = $3 / 4 bagels = $0.75 per bagel

because Donny's unit price is less than that of Bob's (i.e each of Donny's bagels cost less than each of Bob's bagels), thus Donny has the better deal
